I'm flumuxed....as usual.
What makes the points open and close on the DBD34 magneto?
I took a photo, but can't figure out to attach it here.
Thanks, in advance.

Scot,
It looks like you got it right. I believe they call that pin a tappet, made out of non-conducting fibre. Behind the points assy is a face cam. Think of the face cam as a wavy potato chip, with a high spot and a low spot. As the tappet passes over it, the cam raises and lowers the tappet and thus opens and closes the points. Good luck, I just adjusted mine a couple of months ago.
Don't know where the cam starts to open the points, my bike is not readily accessible right now. If you remove the screw opposite the points you should be able to remove the leaf spring and "top" point. You then would be able to push on the tappet and see if it is free to move. These things are easy to work on, they are designed for road side service. The first time I saw the inside of mine was 2 months ago when I adjusted them. I am no mechanical genius but I was able to get it sorted.
